我是PWA的新手,所以请耐心等待,我正在运行龙卷风服务器,这里是注册信息:
if ('serviceWorker' in navigator) {
// Use the window load event to keep the page load performant
window.addEventListener('load', () => {
navigator.serviceWorker.register('/static/js/worker.js');
console.log('Service Worker registered');
});
}
当我选中“应用程序”选项卡上的“脱机”框并刷新该应用程序无法脱机工作时,我放置了一些控制台日志以查看是否触发了获取事件,但似乎什么也没有发生。所有资产均已正确缓存,并验证它们是否存在。看起来最后一点只是使Worker服务器成为正确的缓存文件。
